11. They attribute this relationship to a Bergmann s rule-like pattern for the ectothermic ant. 12. Beyond a frog and a lizard both being clearly ectothermic , they couldn t be any more different. 13. Their endothermic capabilities provided them with a benefit over the mostly ectothermic dinosaurs that dominated the Mesozoic era. 14. They see these as ectothermic animals that adapted to gliding by developing elongated scales and then pennaceous feathers. 15. This process is useful to ectothermic ( cold-blooded ) animals in the regulation of their body temperature. 16. Being ectothermic , the internal body temperature of crocodilians falls as the temperature drops, and they become sluggish. 17. Insects are generally considered cold-blooded or ectothermic , their body temperature rising and falling with the environment. 18. This affects poikilotherms and ectothermic homeotherms ( " cold-blooded " animals ) as well as endothermic homeotherms. 19. Following Bergmann's rule-- unusually, for ectothermic animals-- body size increases with latitude. 20. The developmental period for " D . melanogaster " varies with temperature, as with many ectothermic species.
